The chief worry on the ONCY trial is not the adaptive design. It is the fact they entered a combination Phase III with zero randomized experience with the combination in this disease and very few patients at all treated with this combination in this disease stage.
I dont quite understand your statement above. Randomized experience - does one need experience to administer the same drug to different patients?
I think its a question of how comfortable you are that your drug works and it seemed to them that it may work best in this type of cancer (maybe too simplistic)
